1.添加Maven依赖

<dependency>
    <groupId>com.baidu.disconf</groupId>
    <artifactId>disconf-client</artifactId>
    <version>2.6.36</version>
</dependency>

2.resources/disconf.properties配置

# 是否读取远程配置
enable.remote.conf=true
# disconf HOST地址
conf_server_host=182.92.234.232:9080
# App name
app=springboot-demo
# version
version=V1_0_0
# env
env=local
# 重试次数
conf_server_url_retry_times=3
# 重试睡眠时间
conf_server_url_retry_sleep_seconds=1
# 下载文件的目录
user_define_download_dir=./disconf/download

3.DisconfConfig

@Configuration
public class DisconfConfig {

    @Bean(destroyMethod = "destroy")
    public DisconfMgrBean disconfMgrBean(){
        DisconfMgrBean disconfMgrBean = new DisconfMgrBean();
        disconfMgrBean.setScanPackage("no_used");
        return disconfMgrBean;
    }

    @Bean(initMethod = "init", destroyMethod = "destroy")
    public DisconfMgrBeanSecond disconfMgrBeanSecond(){
        return new DisconfMgrBeanSecond();
    }

    @Bean(name = "reloadablePropertiesFactoryBean")
    @AutoConfigureOrder(Ordered.HIGHEST_PRECEDENCE)
    public ReloadablePropertiesFactoryBean reloadablePropertiesFactoryBean() {
        ReloadablePropertiesFactoryBean propertiesFactoryBean = new ReloadablePropertiesFactoryBean();
        propertiesFactoryBean.setSingleton(true);

        // disconf 配置文件 (这里只有application.properties)
        List<String> fileNames = new ArrayList<>();
        fileNames.add("classpath:application.properties");

        propertiesFactoryBean.setLocations(fileNames);
        return propertiesFactoryBean;
    }

    @Bean(name = "propertyPlaceholderConfigurer")
    public PropertyPlaceholderConfigurer propertyPlaceholderConfigurer(ReloadablePropertiesFactoryBean reloadablePropertiesFactoryBean){
        PropertyPlaceholderConfigurer placeholderConfigurer = new PropertyPlaceholderConfigurer();
        placeholderConfigurer.setIgnoreResourceNotFound(false);
        placeholderConfigurer.setIgnoreUnresolvablePlaceholders(false);
        try {
            Properties properties = reloadablePropertiesFactoryBean.getObject();
            placeholderConfigurer.setProperties(properties);
        } catch (IOException e) {
            throw new RuntimeException("unable to find properties", e);
        }
        return placeholderConfigurer;
    }
}

4.读取已下载的远程文件配置(application.properties)

@Configuration
public class TestConfig {
    public static String username;
    public static String password;


    @Value("${test.username}")
    public void setUsername(String username) {
        TestConfig.username = username;
    }


    @Value("${test.password}")
    public void setPassword(String password) {
        TestConfig.password = password;
    }
}

disconf springboot-demo local application.properties具体配置
    test.username=user123
    test.password=pwd123456

5.测试远程配置文件读取是否成功

@RestController
public class TestController {

    @RequestMapping(name="test")
    public String test() {
        return TestConfig.username;
    }
}

http://localhost:8080/test
